Caecal dysfunction following standing surgical procedures

The aim of this study is to report cases of caecal dysfunction following surgical procedures in the standing horse. The study design is retrospective. Six client-owned horses developed caecal dysfunction following a variety of surgical procedures undertaken in the standing sedated horse. Medical records were reviewed for caecal dysfunctions that had occurred in horses within 2 weeks of standing surgical procedures. Signal ment, details of the original standing surgery and medications administered were recorded. Short-term outcome was obtained from clinical records. Long-term outcome was obtained by telephone questionnaire with the owner. Six horses were identified to have developed caecal dysfunction following standing surgery for tooth extraction, laparoscopic ovariectomy, laparoscopic cryptorchidectomy, fracture repair, melanoma removal and castration. Three horses were euthanised with caecal perforation at the time of diagnosis. Three underwent surgical treatment (typhlotomy, decompression and caecal bypass by ileocolostomy). All three horses were alive post-operatively (follow-up at 2, 12 and 24 months). Caecal dysfunction may develop following surgical procedures performed under standing sedation. Careful post-operative monitoring and early identification of caecal dysfunction, and consequent potential need for surgical intervention, are important to optimise outcomes and minimise the risk of fatal caecal perforation occurring.
